My dad tried to last summer, but luckily my mom found him passed out on the floor overdosed on pills. Shaved his head and mustache to make it "easier" on everyone. Thinking we wouldn't recognize/take it as bad since it didn't look like him as much. Depression is not very logical when you reach that point.
Talked about doing it the "right" way after that (gun, etc.) for a bit after that while being in the psych ward of the hospital.
I know I am like him a bit in that way as I have bouts with depression as well but not nearly like I used to. Not to turn this into a religion thread (please don't in the way it happens on these forums) but I have a reason to live so I've never taken it that far.
